A leader of fashion gets it at the gym, perhaps (3)
I believe the answer is:
fit
'the gym perhaps' is the definition.
I can't judge whether this definition defines the answer.
'a leader of fashion gets it' is the wordplay.
'a leader of' suggests taking the first letters.
'gets' is a charade indicator (letters next to each other).
The initial letter of 'fashion' is 'f'.
'f'+'it'='FIT'
'at' acts as a link.
Can you help me to learn more?
(Other definitions for fit that I've seen before include "Of a suitable standard" , "Suitable; sudden attack" , "Adequate" , "Appropriate kind of convulsion" , "Be the right size or shape" .)
